Patent DE-2920663-A1 (DE)
Title: Sewing machine needle brake adjustment - varies braking forces between stitches according to type of stitches
Inventor: ENGEL WOLFGANG ING GRAD
IPC: D05B47/00
Filed: 1979-05-22
Abstract: To adjust the needle brake mechanism according to the type of stitch to be sewn, the required needle braking force is developed from the horizontal and vertical gap between stitches before the upper and lower threads have been knotted in the fabric for the next stitch. There is a proportional signal for the first stitch and the next stitch according to the position of the needle shaft. These signals are stored in sequence in a temporary store. Similarly for the advance slide, proportional signals for the first stitch and the next stitch are fed to another store. There are separate computers to develop difference signals. The system gives an automatic adjustment of the needle braking action, independent of the pattern control mechanism.

Title: Sewer rake grating guided cleaning comb - has ascending path aligned to bring prongs just short of bars
Inventor: ROMPF ERHARD
IPC: E02B8/02
Filed: 1979-05-28
Abstract: A comb is mounted on a moving device, for its teeth to pass through a rake grating built into a sewer, for cleaning, and then move upwards. The rising track of the comb is aligned in relation to the grating bars so that the prong tips approach these in the course of movement upwards, but do not quite reach them. The comb may follow a vertical path along the grating, which has bars sloping from the foot against the direction of flow. The system ensures that material on the comb is promptly brought together, simplifying its unloading.

Patent DE-2936399-A1 (DE)
Inventor: KOSKE PETER DR
IPC: C22B60/02
Filed: 1979-09-08
Abstract: The processes and devices known heretofore for removing valuable materials dissolved, particularly uranium oxide, in sea water passing through absorbing layers have not yet met any success in the implementing thereof, because of the suspension materials in water in areas close to the coastline and because of the high energy required for pumping sea water at high levels. To provide a practicable removal process with high efficiency and low energy consumption, it is proposed to arrange the absorbing layers into elements shaped like floating pontoons on sea and to pass sea water therethrough by means of pumps.

Patent DE-3010014-A1 (DE)
Inventor: LORENZ WERNER DR ING
IPC: F23N1/06
Filed: 1980-03-15
Abstract: A burner having an air intake at atmospheric pressure, a gas (fuel) supply line and a combustion chamber in which gas from the latter line burns in the presence of atmospheric air drawn in from the intake, is provided with a swingable or rotatable flap-type valve member which controls the volume rate of flow of the air to the combustion site. According to the invention, the position of the valve member is controlled by a parameter generated by the air stream and in response to the pressure in the gas supply line to maintain the air factor (ratio of air to gas) substantially constant. To this end a membrane type pressure detector responds to the pressure in the gas supply line and is connected by a mechanical force transmission mechanism to the flap or other valve element.

Patent DE-3021320-A1 (DE)
Inventor: LINDENMYER HEINZ
IPC: B25D17/08
Filed: 1980-06-06
Abstract: A control sleeve (7) for locking and unlocking the tool is allocated to the tool holder. The tool holder contains recesses for locking elements which project to a limited extent into the interior of the tool holder, have a displacement clearance space radially to the outside as well as axially, and in the locking position engage in corresponding grooves of the tool shank. At its inner periphery, the control sleeve (7) is provided with groove-shaped longitudinal recesses (21, 21') for the partial engagement of the locking elements, and the tool holder, in the area of its outer circumferential surface, has locking recesses for a catch member (8) located in the control sleeve and under spring tension. The control sleeve (7) has at least one cam-shaped prominence adjoining each groove-shaped recess (21, 21') in the peripheral direction and allocated to each locking element. The cam-shaped prominence is arranged axially in such a position relative to the longitudinal recess (21, 21') that the locking element can be displaced from its rear position towards the tool side by acting on its rear end upon rotation of the control sleeve (7). <IMAGE>
Patent DE-3022830-A1 (DE)
Title: Thread spooling device - has outer carrier to form spool by centrifugal forces from the outside inwards
Inventor: SCHUSTER FRIEDRICH DIPL ING
IPC: B65H55/04
Filed: 1980-06-19
Abstract: The carrier to form the spool of thread or yarn surrounds the wound material as the spool is built up. The process allows higher winding speeds than are possible when winding round a central core, as centrifugal forces exert a limiting effect. The body of the wound spool is developed from the outside inwards, and the material is extracted from the centre of the wound spool. As the carrier rotates, the thread is fed in by a guide to the interior to be laid against the inner surface of the carrier by centrifugal forces,with the guide moving axially up and down at a constant or irregular speed. The carrier rotates at a constant or variable speed. The thread laying speed is independent of the carrier speed, to give a wound spool which is cylindrical or conical, in parallel or cross windings or in loop windings. The thread can be moisture treated, to increase its friction coefficient, or given a wet and/or dry adhesion treatment, before the thread is wound.

Title: Accurate master positioning for graphic copier - using electron elements at correct height for focussing and thus avoiding parallax errors
Inventor: RUEDIGER JOHANNES
IPC: G03F9/00
Filed: 1980-10-27
Abstract: The positioning arrangement can be used in multiple colour systems requiring successive masters for different colours to be used.
